Solvent recovery plants

Listing ID #3623265

Solvent plays crucial role in modern society. However, complete world’s production of solvent ends up by being destroyed or dispersed in biosphere. Solvents are the source of about 35% of the Volatile Organic Compounds (VOC). Industrial Processes emit solvent vapours in large quantities. These emissions are harmful to environment as well as public health and shall be subject to stringent statutory norms in near future. So, emitted solvent vapour need to be recovered to reduce the harm it is causing to the environment, also it has attractive market value.
Our Solvent Recovery systems employ modern distillation technology to separate and recover valuable chemical products from waste mixtures. Using our systems, you can recover and reuse solvents from a wide range of processes – even from complex mixtures with high variability from batch to batch.
Generally there are FOUR methods for solvent recovery and they are as follows:

• Distillation
• Liquid-liquid extraction
• Steam stripping
• Absorption

Out of these four processes we only focus on distillation process. Distillation systems are used to separate and recover high purity solvents suitable for reuse. OUR distillation system can provide both batch and continuous process. We are also involved in trading of solvent. We are the preferred choice by customers in the chemical, pharmaceutical, and other specialty industries around the world for recovery, recycle and reuse of solvents.

PROCESS DISCRIPTION:
Waste solvent which is to be recovered is heated in the kettle/reactor. Heated (contaminated) solvent is then sent to the distillation column where the separation takes place on the basis of difference in boiling point of the two liquids. Vapors so formed are condensed in primary condenser and the remaining uncondensed vapors are condensed in secondary condenser. Condensate (solvent) is collected in receiver tank which packed, sold and reused . Impurities present in the waste solvent settled down because of sedimentation and drained off from the bottom of the reactor.
MPL provides atmospheric, vacuum and azeotropic multi-component distillation systems to separate and purify solvent mixtures.

The ranges of solvent includes that are distilled are as follows :

Low boilers:

• Acetone
• Toluene
• IPA(isopropyl alcohol)
• MDC
• Methanol
• Ethyl acetate

High boilers:

• Sulfolane
• Phenol
